Application filed September 3, 19%.

To all whom it mag/concern.

Be it known that 1, JOHN T. CosTnLLo, a resident of Pittsburg, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Plumbing-Traps; and I do hereby declare thefollowing to be a full, clear, and exact description thereof.

My invention relates to plumbing traps, and has special reference to atrap for use in connection with wash-stands, tubs, sinks and othersimilar articles.

The object of my invention is to provide a trap which will be cheap,simple and ef ficient in its form and operation, will do away with theformation of cored openings for the water supply pipes in the stand,tub, etc., and will provide for what is known as a perfect roughing injob in setting up the trap.

My invention consists, generally stated, in the novel arrangement,construction and combination of parts, as hereinafter more specificallyset forth and described, and par ticularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains toconstruct and use my improved trap, I will describe the same more fully,referring to the accom Figure 1 is a vertical central section of myimproved trap showing the same applied to a wash-stand and with some ofthe parts in full lines. Fig. 2 is a front view of the same. Fig. 3 isan enlarged vertical section of the trap. Fig. 4 is a like section ofthe same taken on the line l4 Fig. 3. Figs. 5, 6, 7 and 8 are detailviews showing the manner of supporting the stand in place. Figs. 9 andare modifications of the device.

Like symbols of reference herein indicate like parts in each of thefigures of the drawing.

' As illustrated in the drawing. 1 represents the usual wall of abuilding and 2 is a wash stand of any approved construction having thebowl 3 and rim 4 around the upper portion of the same. Within the wall 1is the trap 5, which is preferably formed of cast metal and of box-shapehaving a partition wall 6 extending centrally and vertically from theupper end 7 of the same to within a short distance of the lower end 7 toform the space 8 under the same. The partition 6 forms the chambers 9and 9 on each side of the same and leading down within the Specificationof Letters Patent.

wall 1 from the rear chamber 9 and above the lower end of said partitionand space 8 is the waste or escape pipe 10 from the trap Connected tothe upper end 7 of the trap 5 and through a boss 11 thereon is the ventpipe 12, which communicates with the chamber 9 and extends up within thewall 1 to the atmosphere in the ordinary manner.

Cored out of the front side of the trap 5 and within the chamber 9 isthe supply passageway 18, which has an elbow portion 1% thereon forextending through the wall 1 and for being connected to the supply pipe15 for the stand 2. Leading from and connected at one end to the usualopening 3' in the bottom of the bowl 3 is the usual waste pipe 16, towhich the pipe 15 is connected and which acts as a combined supply andwaste pipe. The other end of the pipe 16 leads into the bottom of thetrap 5 through an elbow 16 connected thereto which passes through thewall 1 and through an extension 16 on the end 7 to which such elbow isconnected. An overflow pipe 17 leads from one side of the extension 16and up within the chamber 9 of the trap 5 and its upper end opens withina short distance of the upper end 7 of said trap.

A seat 18 is formed in the lower end 7 of the trap and over the openingformed by the extension 16 thereon, and a plug 19 is adapted to engagetherewith and be operated through a rod 20 which is connected theretoand extends up through the chamber 9 and into a box 21 supported in thefront portion of the wall 1. The rod 20 passes through a pipe 22 whichis connected to the upper end 7 of the trap 5 and to the lower end ofthe box 21. as well as passing through a. stuffing box 21 on said boxend, and a bar 20 is connected. to the upper end of said rod and passesthrough an opening 20 in the front wall of said box. A locking oroperating plate 28 is pivoted to the outer end of the bar 20 and isprovided with a hole 23 in the same for engaging with a hook pin 24extending out from the upper portion. of said box and above the opening20.

Connected to the upper end 7 of the trap 5 and communicating with thepassage-way 13 in said trap is the main supply pipe 25, which leads upfrom said trap and is provided with the usual branch pipes 26 at theupper end of the same. These two ranch pipes 26 have the usual faucets27 at their ends which extend through the front portion of the wall 1,and are preferably provided with the hand wheels 28 at their outer endsfor operating the same to supply hot or cold water to the pipe 25, asdesired, from the main or other supply pipes (not shown) in the wall 1and leading into said faucets.

A projecting portion or extension 29 is formed on the front of the trap5 and at the lower end of the same, which extends through the frontportion of the wall 1 and is provided with a screw-cap 30 at its outerend for enabling the cleaning out of the said trap, when desired.

Extending around the vent pipe 12 and against the boss 11 on the upperend 7 of the trap 5 is the U-shaped bracket 32 for locating andsupporting the stand 2, which has a hole 32 in a base 32 on its bodyportion 32 for fitting around said pipe. The arms 33 on the bracket 31extend through the front portion of the wall 1 and are adapted to passthrough openings 34 in the rim 4: on said stand so that dovetailed lugs35 on the ends of the arms 33 can fit within dovetailed seats 35 on therim 1 of the stand 2 and support said stand in position.

As the wall 1 is formed or built up, the trap 5 is set within the sameand when the wall is completed at such point, the trap has the escapepipe 10 and vent pipe connected thereto, and with bracket 31 and theoperating parts of the trap in position for use, the said trap is readyfor its being connected up to the stand 2, which is accomplished in thefollowing manner. The stand 2 is conneeted to the bracket 31 set inposition on the trap 5 and around the vent pipe 12 by dropping the same,so that the openings 34 in the rim 4 on said stand pass over the arms 33on said bracket and allow the lugs 35 to fit within the seats 35 on saidrim. The stand 2 is now ready and in position for waste pipe 16 to beconnected to the elbow 16 on the trap 5 extending through the frontportion of the wall 1 from the extension 16 on said trap, and the supplypipe 15 to be connected to the elbow 14: on the passage-way 13 extendingthrough said wall portion. after which the pipe 15 can be connected tothe waste pipe 16 and said pipe 16 connected to the opening 3 in thestand bowl 3.

The use and operation of my improved plumbing trip are as follows: Byopening one or both of the faucets 27 through the handle or handles 28,the water will pass from the main supply pipe or pipes to the pipe 25through the branch pipe or pipes 26 and thence down through thepassage-way 13 in the trap 5 into the bowl 3 through the pipes 15 and16. In case of any overflow in the bowl 3, the water will pass downthrough the pipe 16 and into the overflow pipe 17 in the trap 5, afterwhich it will flow out the top of said pipe 17 into the chamber 9 ofsaid trap, and then enter the water seal a formed in the bottom of saidtrap by the partition 6 therein and below the opening in said trap tothe escape pipe 10, so that any excess of water formed thereby in saidseal can enter said opening and pass away through the said pipe 10.After the supply of water to the bowl 3 has been shut oh", the waterwithin said bowl can be emptied from the same by raising the plug 19from its seat 18 through lifting of the rod 20 connected thereto and bar20 connected to said rod. so that these parts can be thus held in thesepositions by hand through said bar or by turning the plate 23 on saidbar and allowing it to engage with the hook pin 24: through the hole 23in said plate, thereby holding said parts in said positions. By thusraising the plug 19, the waterwithin the bowl 3 will pass down andthrough the waste pipe 16, around the plug 19 and into the seal a in thetrap where any excess of water formed thereby can enter said opening andpass away through the escape pipe 10.

hen it is desired to clean the seal a and pipe 16, the plug 10 can beraised and a cloth or other cover placed over the opening 3 to said pipein the bowl 3, so that with the water turned on, the clean or freshwater will pass from the pipe 15 through the pipe 16 and out through theescape pipe 10. After the waste water in the bowl 3 has passed out thetrap 5 through the pipe 16, the fresh or clean water remaining in thepipes 25, 26, passage-way 13 and pipe 15, will seep or drip through thepipe 16 and further aid in cleaning the seal a of the trap 5.

If desired, the overflow pipe 17 can carry the plug 19 at the lower end,and the rod 20 connected to the upper end of the same, as shown in Fig.9, so that by lifting on said rod the pipe and plug will be raised withthe same, and if desired the partition 6 can be dispensed with, and insuch case the pipe 22 can extend through the upper end 7 of the trap andinto the water forming the seal a at the lower end of said trap, asshown in Fig. 10, while various other modifications and changes in thedesign and operation of my improved plumbing trap may be resorted towithout departing from'the spirit of the invention or sacrificing any ofits advantages.

It will thus be seen that in the use of my improved trap the supply andwaste to and from the stand, tub, sink, etc., take place at a singleopening therein, which is generally termed the waste opening, and

through what is known as the waste pipe,

ture or article for the supply pipes, and at the same time overcomingthe necessity of fitting up such pipes to the article, which istroublesome and expensive by reason of the pipes being out of alinementor requiring cutting 011', etc.

It will also be seen that my improved trap when in use will provide forpositive connections, will be sanitary in all respects, and will providefor a complete roughing in job in every way, while at the same time theplug will be in the trap instead of in the article, and all parts arecompletely covered up when in use.

When the trap is used with a wash-stand, such stand can be gaged andpositioned for being connected to the trap, easily and quickly, and willnot require the use of rigid and expensive connections for the same,while the overflow being in the trap will do away with the use of acored overflow in such stand, which is expensive and troublesome to makeand is very unsanitary, by reason of its collecting dirt and slime andallowing foul air to escape therefrom into the room or apartment inwhich it is used.

It will also be obvious that all the parts pertaining to the stand orfixture are in one perfect position to receive such fixture and arelocated in the wall or partition in the rough of a building, while thetrap will necessitate the control of the supply pipe and b so doin allowa combined suo l a l p and waste pipe connection, so that thisconnection compels the plug or stopper for the fixture to be placedbeyond such fixture and in a trap in connection with the overflow insuch trap for such fixture, thereby providing a trap which has theoverflow or part of the fixture in the same and forming a trappedoverflow. The overflow is water sealed and sanitary by being located inthe trap and not in the fixture and the plug or stopper being located inthe trap and not in the fixture enables full control from the wall pullto operate the same. The trap screw or cap is sealed or trapped by thewater in the trap and through the partition in said trap, and such trapcan be easily cleaned through the opening closed by said cap.
